Prince William has returned to work after a summer holiday with his family, adding fuel to the rumours surrounding wife Kate Middleton’s absence.

The Duke of Cambridge met with firefighters in South London on Thursday in honour of Emergency Services Day.

But, his appearance without the Duchess of Cambridge – who has not been seen for more than 60 days – has prompted royal fans to speculate whether she may be pregnant.

Kate was last spotted on July 11, when she attended the Euro 2020 football final with her husband and eldest son Prince George.

She has been notably absent from social media as well, with the most recent image on the couple’s account having been posted on August 6.

However, the photograph showing Kate speaking with a Holocaust survivor is believed to be from January last year.

Royal commentator Russell Myers has since put the pregnancy rumours to bed, saying her recent absence has been due to the family’s summer holiday.

Speaking to Today, Myers said the pregnancy rumours seemed to be more “mischief making” than based on actual facts.

“What I can exclusively reveal… probably nothing,” he said.

“The duchess isn’t pregnant. I think some people have been asking the question of where has Kate been. But where the truth really lies is, they’ve been on holiday.

“There’s normally an agreement between the press and the royals that if they are on holiday that the kids don’t get followed around,” Myers explained.

“Photographers leave them alone during the holidays. They’ve been up in Norfolk. They’ve been chilling out. They’ve been up to see Granny up in Scotland.”

Kate’s recent disappearance comes after she vanished from the public eye for 41 days last year, while she and William were on holiday in Wales.
